Question

Nine less than 4 times a number is the same as twice the number increased by 11. What is the unknown number?

Answer 1

4x-9 = 2x+11

Answer 2

4x-9= 2x+11
Lets add 9 to both sides
4x-9+9= 2x+11+9
4x= 2x+20
Subtract 2x from both sides
4x-2x=2x-2x+20
2x=20
x=10

Answer 3

where x would be the number, this would be the linear equation required.

Answer 4

let them solve on their own!!

Answer 5

WHAT

Answer 6

Ok so your equation says: nine less than 4 times a number is the same as twice the number increased by 11. What is the unknown number?
so we are using x as "the number"
so the first part of the equation says 9 less than 4 times the number so we do 4x-9, do you get that so far?

Answer 7

no not really

Answer 8
